T0 at whom it may-concern:

Be it known that I, JAMES L. TURNER, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Lawn-Sprinklers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to portable lawnsprinklers, and has reference particularly to the nozzle whereby the spray may be produced, one object of the invention being to provide a simple, cheap, and durable sprinkling-nozzle which shall deliver considerable water rapidly and so as to spread and cover the max "1m area without elevating the water objeotlo'nably in the air-currents.

A further object is to provide a sprinklingnozzle which shall not be liable to derangement or damage through careless handling and which shall be free from such delicate parts as might become clogged and inoperative by accumulations from the water.

Referring to the drawings, Figure 1 represents a side elevation of my nozzle attached to a sled-shaped stand; Fig. 2, a perspective View of the nozzle Fig. 3, a horizontal sectional view on a line X X in Fig. 1, showing the upper end of the partitional wall or core which partly forms the spiral duct; Fig. 4:, a vertical central sectional view of the complete nozzle, showing broadlyits principal features; Fig. 5, a vertical central sectional view of the nozzle-shell, the lower part of which is broken away and showing a modification in the details of construction; and Fig. 6, a view in elevation of the core substantially as it appears when form ed separately from the nozzleshell.

In construction I provide a suitable metallic nozzle-body A, of cylindrical form, having an enlarged open base a, in which are cut suitable threads 6, adapted to engage either a hose-fitting or a stand B, having an inletpipe elbow b and also a projection is, adapted to receive the base a. The body A has a cover or cap 0 of circular flat form, in the center of which is an orifice d. If desired, the body may have a jointj near the cover 0, in which case one part of the body has external screwthreads m and the connecting part has internal screw-threads n, engaging the other threads and cut in an enlarged portion G, so that the interior of the chamber E may be readily finished true and smooth separately if the core D is formed integral with the body A before attaching the cover to the body, and the cover may be removed at any time in order to attach an ordinary jet-nozzle to the body.

In the body A is a core D, extending from a point h, near the lower or base end, to a point 'i, somewhat near the cover 0, so as to leave an unobstructed circular chamber E below the cover, the core being in the form of a spiral thread projecting inwardly from the wall of the body A to about the center of its diameter, so that the wall of the body forms the outer confines of a spiral duct F, comprising the space between the coils of the core. This partition or core D may be made integral with the body A, or the body may have a clear interior f and the core be made separately and pressed into the body and retained by frictional resistance or otherwise.

It should be observed that the under face of the flat cover 0 is in a plane at a right angle to the axis of the nozzle, so that it acts as a baffle to the water as it emerges from the duct.

In practical use the water enters the base and passes through the spiral duct F to the chamber E, in which it expands and is broken up, the spirality of the duct causing it to acquire a centrifugal motion in the chamber, from which it is forced (the water being assu med to be under pressure) through the orifice d in a whirling spray in all directions radially and rising only to a moderate height.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. A lawn-sprinkler comprising a body portion having a cylindrical interior, a spiral core rigidly attached to the interior of the wall of the body portion and extending inwardly from said wall toward, and substantially to, the axis of said body portion, and a cover having an orifice therein removed from one end of such core, substantially as set forth.

2. A lawn-sprinkler consisting of a cylindrical body portion having screw-threads at one end thereof and a cover having an orifice at the opposite end thereof, and a spiral core rigidly attached to the wall of said body por tion and extending inwardly from said wall toward, and substantially to, the axis of said body portion and longitudinally from a point near one end thereof to a point near the opposite end thereof, substantially as set forth.

3. A sprinkler-nozzle consisting of a cylindrical body havinga smooth bore, a cover having an orifice, and a core rigidly attached to the wall of said body and extending as a spiral
